UI hosts national workshop on rainfall measurement

IOWA CITY, Iowa -- How do you measure a raindrop?

That question and others will be discussed at a Nov. 5-6 technical workshop being hosted by the University of Iowa College of Engineering's Iowa Institute of Hydraulic Research (IIHR) at the Wind Tunnel Annex, 130 W. Harrison St.

The workshop is being held to give about 20 hydrometeorology experts from across the country hands-on experience in operating an instrument called a "2-D video disdrometer" that measures the size and distribution of raindrops, as well as other raindrop data. The UI instrument, manufactured by Joanneum Research of Austria, is one of only two in the United States, with the other one owned by NASA.

The workshop will provide training and exchange of information for researchers who are preparing to participate in an experiment studying climate change. The experiment, sponsored by NASA, will be held in the Amazon in Brazil.

According to Anton Kruger, IIHR researcher and workshop organizer, IIHR's hosting of the workshop is a clear recognition of IIHR's contributions to the field of radar and satellite remote sensing of rainfall.

In addition to IIHR's hydrometeorology group, workshop participants will represent Colorado State University, NASA, the National Oceanic and Atmospheric Administration, the National Center for Atmospheric Research, the National Severe Storms Laboratory, and the Hydrologic Research Center.
